WILLIAM M. STEVENSON, OF SPRINGFIELD, MASSACHUSETTS.

WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 658,293, dated September 18, 1900.

To aZZ whom it may concern:

Be it known that I, WILLIAM M. STE VENSON, a citizen of the United States, and a resident of Springfield, Massachusetts, have invented certain Improvements in Woven Fabrics, of which the following is a specification.

The object of my invention is to provide a durable and attractive woven fabric for carpets, rugs, upholstery, or like uses, said fab ric having independent face and back plies firmly bound together and having on each face a pattern of pleasing efiect produced'by a simple method of weaving and by the combination of a single set of figuring warpthreads with the weft-threads of the front and back plies of the fabric.

In carrying out myinvention I prefer to use for the weft-threads twisted strands of paper, as in the single-ply fabric forming the subject of my application, Serial No. 2,324, filed J anuary 22, 1900, so that the textile figuring warp-threads will, owing to the incompressi-v bility of these paper weft-threads, be brought prominently into relief on the faces of the fabric, although my invention may be embodied in a fabric in which textile weft-threads are employed instead of such paper weftthreads.

In the accompanying drawings, Figure 1 is a face view of a piece of fabric embodying my present invention. Fig. 2 is a view of the corresponding portion of the back of the fabric. Fig. 3 is an exaggerated section of the fabric, taken in the direction of the warp. Fig. 4. is a like section of the fabric, taken in the direction of the weft; and Fig. 5 is a view similar to Fig. 3, but illustrating a fabric which, while structurally similar to that of said Fig. 3, has greater diversity in coloring.

Each of the fabrics shown and described comprises a face web or ply consisting of weft-threads 1 interwoven with warp-threads 2 and a back ply similarly composed of weftthreads 3 interwoven with warp-threads 4, each of these plies being thus structurally complete in itself and independent of the other. In connection with the two plies of fabric thus produced I use a set of figuring warp-threads 5, by preference considerably larger or heavier than the warp-threads 2 and 4, these figuring warp-threads alternating with the finer warp-threads and being carried Application filed J'une19,1900. SrialNo.20,84=4. (No specimens.)

from one face of the fabric to the other in accordance with the requirements of the pat tern, so that they not only perform their intended patterning duty on each face, but also serve to firmly tie or bind together the face and back plies of the fabric, thereby rendering the latter firm in texture and durable in character.

In order to preserve purity or solidity of colorin gin the pattern,each of the weft-threads of the fabricis by preference bound or crossed on the face by a warp-thread of corresponding color. For instance, in the fabric shown in Figs. 3 and 4; the weft-threads 1 of the face ply may be red, the warp-threads 2 being also red,while the weft-threads 3 and warp-threads 4 of the back ply may be white. Hence if the figuring warp-th reads are green a pattern in green and red will. be produced upon one face of the fabric and a reverse pattern in I green and white on the opposite face. Greater diversity of coloring may, however, be obtained by using in either or both plies alterna'te weft-threads differing in color and likewise coloring the warp-threads, so that each weft-thread will be crossed or bound on the face by a warp thread of its own color. For instance, the weft-threads and warp-threads may be alternately red and white. Thus in Fig. 5 each ply is composed of alternate red weft-threads 6 and white weft-threads 7, interwoven with alternate red warp-threads 8 and white warp-threads 9, the red warpthreads crossing the faces of the red weftthreads and passing behind the white weftthreads and the white warp-threads crossing the faces of the white weft-threads and passing behind the red weft-threads.

In carrying out myinvention I can produce by a simple method of weaving and in a simple form of loom a fabric having opposite faces widely differing in appearance, this difference being due partly to the reversal of the pattern and partly to the change in coloring of the weft-threads of the two plies.

Having thus described my invention, I

.claim and desire to secure by Letters Patent l. A woven fabric composed of interwoven warp-threads and weft-threads forming two independent plies and a single set of figuring warp-threads which passes from face to face of the fabric, but not between the plies whereby it performs the double duty of patterning each face in relief and tying the two plies of the fabric firmly together, substantially as specified.

2. A woven fabric comprisingindependent face and back plies each consisting of weftthreads of alternating colors and warp-threads of like alternating colors, whereby the face of each weft-thread is crossed by a warpthread of corresponding color, and a single set of figuring Warp-threads passing from face to face of the fabric but not between the plies whereby it serves the double duty of patterning in relief on each face and of tying the two plies of the fabric firmly together, substantially as specified.

3. A woven fabric consisting of weft-tl1reads of paper interwoven with warp-threads to form two separate and independent plies and a single set of figuring warp-threads of textile material, said warp-threads passing from face to face of the fabric but not between the plies, and serving to form a pattern in relief on each face and also to tie the two plies of the fabric firmly together, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM M. STEVENfiON.
